Assets linked to one of 'Putin's favorite oligarchs' include a private Airbus jet and one of the world's largest megayachts take a look

Usmanov — who has been described by the EU as "one of Vladimir Putin's favorite oligarchs" — founded USM Holdings in 2012 and retains a 49% stake in it, Insider's Grace Dean previously reported.

The holding company has investment interests in metals, mining, telecoms, and technology, according to its website, and owns a company which claims to be Russia's largest iron-ore producer.

The billionaire — whose net worth is estimated at $14 billion, according to Forbes — also said he has invested around $880 million in Facebook.

Usmanov owns Beechwood House in Highgate, North London, which is estimated to be valued at around £48 million, or $62.9 million, according to the UK government.

The UK sanctioned Usmanov on March 3, stating that the oligarch — as well as another, Igor Shuvalov — would be "cut off from their significant UK interests including mansions worth tens of millions."

But a spokesperson for Usmanov later told The Guardian that the billionaire's UK property holdings had been transferred into "irrevocable trusts," and Usmanov no longer held beneficial rights over them.

"From that point on, Mr. Usmanov did not own them, nor was he able to manage them or deal with their sale, but could only use them on a rental basis. Mr. Usmanov withdrew from the beneficiaries of the trusts, donating his beneficial rights to his family," the spokesperson said, according to The Guardian.

The trusts cannot be amended after creation, and since Usmanov reportedly no longer owns them, properties like Beechwood house could be out of the government's reach, Insider's Huileng Tan previously reported.

A spokesperson for Usmanov did not immediately respond to Insider's request for comment on his link to the property.

The UK government said that Usmanov owned Sutton Place, a 16th-century estate located in Surrey, in the south of England.

The property is estimated to be valued at $40.5 million and is listed as a Grade I historic building, according to the OCCRP's asset tracker.

The mansion was owned by a series of wealthy men in the 20th century, per OCCRP, including the oil magnate J. Paul Getty.

The estate is not listed as belonging to an individual but instead to two companies in Cyprus, according to the tracker. A recent investigation by the Financial Times found a number of business links connecting Usmanov to the property, but could not trace it directly back to him.

A spokesperson for Usmanov told Insider that Sutton Place is not "owned or used by Mr. Usmanov."

"It is the property of the trusts whose beneficiary is his sister, and who has a family of her own. We have already stated that long ago, Mr. Usmanov transferred his real estate and other property into irrevocable family trusts. We have also emphasised that this had nothing to do with sanctions or an attempt to hide anything, but was driven by the wish to care for his relatives," the statement added.

The spokesperson said that Usmanov started to establish trusts 15 years ago, renouncing any rights he held to the assets he transferred into them.

It is not clear when the assets related to Sutton Place Estate were transferred into the trust.

The oligarch also has an interest in sport.

He previously held a 30% stake in English soccer club Arsenal, which he sold in 2018. His holding company, USM Holdings, also sponsored Everton soccer club's training ground, and paid £30 million ($39.4 million) for the naming rights to its new stadium, Insider's Grace Dean previously reported.

Everton suspended the sponsorship links with USM Holdings on March 2, according to a statement on the club's website.

Usmanov has also been linked with a $600 million superyacht, Dilbar.

According to the US Treasury, Dilbar is named after Usmanov's mother.

The vessel is the "largest motor yacht in the world by gross tonnage," according to its manufacturer, Lürssen, weighing 15,917 tons and stretching to 512 feet.

It also has the largest pool installed on a yacht, at 82 feet long, according to Lürssen.

The yacht was seized by Germany's Federal Police on April 14 after they ascertained it was owned by Usmanov's sister, Gulbakhor Ismailova.

Ismailova has also been added to the EU sanctions list, which says that Usmanov "indirectly transferred assets," including the megayacht, to her.

According to the EU, Usmanov in 2017 ceased to be a shareholder in the trust company that indirectly owns Dilbar, leaving Ismailova as "the only beneficial owner of the yacht."

The yacht has been docked in Hamburg, Germany, for months. Forbes originally reported that the yacht had been seized in Germany but later issued a correction.

The crew of the megayacht were later dismissed as sanctions meant their wages could not be paid.

Usmanov has also been linked to a black Mercedes-Maybach S650, which was detained in March by authorities in Sardinia, Italy, Insider's Kate Duffy previously reported.

The vehicle — which is reported to be fitted with armor plating and bulletproof glass — weighs five tonnes and is worth around 600,000 euros ($670,000).

Sardinian authorities did not immediately respond to Insider's request for comment in relation to the reports of the car's seizure.

Mercedes said the vehicle can withstand the force of two hand grenades exploding at the same time, according to The Times.

Mercedes did not clarify the vehicle's features in a statement sent to Insider.

Usmanov also owns an Airbus A340-300 which is estimated to have cost between $350 and $500 million, according to the US Treasury.

The aircraft is one of the largest privately owned planes in Russia, and is named Bourkhan, after Usmanov's father, according to the Treasury. The Treasury also said that the plane's registration, M-IABU, stands for "I'm Alisher Burhanovich Usmanov."

A spokesperson for Usmanov did not immediately respond to Insider's request for comment in relation to Usmanov's link to the aircraft.

The billionaire is also linked to a number of villas along the Mediterranean coast of the Italian island of Sardinia, which are not registered to him, but rather to offshore companies, according to OCCRP's tracker.

The cluster of five villas is located in a coastal area within the municipality of Arzachena in Sardinia, per the tracker.

One villa — which is valued at $5.9 million — is owned by Usmanov's sister Gulbakhor Ismailova, while another — valued at $6.9 million — is owned by an Italian company, which is in turn owned by a Bermudan company belonging to Usmanov, called Pauillac Property Limited, according to the OCCRP tracker.

According to the EU's sanctions list, Ismailova has "been linked to luxury real estate in Italy and Latvia, that can be linked to her brother Alisher Usmanov."

A spokesperson for Usmanov did not respond to Insider's request for comment in relation to his link to the properties in Sardinia.
